Having a bit of a dilemma here. I am going to be cooling an AMD FX-8320 with an H80i, and have SP120 fans, and AF120 fans, which should I put on replace the original fan with? The reason I am asking is because the AF120 I have is an LED fan, and I want to see it in my build. I know that the AF is for air flow, and the SP is for static pressure, but really what's the difference? And what do you recommend I should use for my CPU cooler?
